SPECIFICATION l forming part of Letters Patent No. 664,253, datedDecember 18, 1900.

Application filed July 3, 1897. Serial No. 643,335. ALINO modelo To @ZZwhom it may concern.-

Beit known that we, ANDREW E. GAGNON and HENRY J ONOAS, of Minneapolis,Hennepin county, Minnesota, have invented certain new and usefulImprovements in Knotters for Binders, of which the following is aspecication.

Our invention relates to machines for binding laths oi' like products inWood and also to grain-binders and in general to all machines which windor bind a cord or band about a bundle and tie a knot with the ends ofthe cord. KThere are many machines of this general class and many whichsatisfactorily perform the service required in binding grain or likecolnpressible stuff which will expand and .fill the loop or encirclingband; but up to the present time no successful machine for bindingsuchincompressible materials as Wood or metal in bars or sticks has beenproduced to our knowledge.

It is one Object of our invention to prov-ide a binder and knotterwhich, in addition to tying a very tight knot, will draw the cord or'band firmly around the bundle and leave the cord under tension beforethe 'material is removed from the compressor, which is used to hold thebundle in form while being bound; and it is a further object of ourinvention to provide such a positive device which, While speciallyadapted for binding laths in a bundie Or bundles or any incompressiblearticle, will by its lightness and coinpactness of form be equallyadapted for use in binding grain and the like and willshow amarkedimprovement in that special branch of the art.

The leading and most definite objectof our invention is to provide aknotter which after forming the loop, which may be done in many ways,will hold the ends of the cord and roll or force the untightened knotclose up to the bundle and thentighten the knot, placing the cord undertension, and leaving the knot against the bundle so firm and strong thatit cannot become untied or loose and open.

Our invention consists inthe combination, with suitable means forpassing or wrapping the cordv or band around a bundle, of means forforming a loop in the cord and for drawing the ends .of the cord throughthe loop to form the untightened knot and a device or part closing uponthe cord on that side of the untightened knot opposite the bundle, thedrawing and closing means being relativelyy movable to cause theuntightened knot to be rolled against the bundle.

Our invention further consists in improved means for tying the knot andfor cutting the cord, and, further, our invention consists in particularconstructions and combinations of parts, all as hereinafter described,and particularly pointed out in the claims.

The invention will be more readily understood by reference totheaccompanyingdrawings, forming a part of this specification, and

in which- Figure 1 is an end elevation of a knotter embodying ourinvention. Fig. 2 is a side view thereof .in section on the line .It mof Fig. 1. Fig. 3 is an end section on the line yy of Fig. 2. Fig. 4 isasimilar section on lineman of Fig. 2. Fig. shows the inner face of themoved back and forth intermittently. Fig. 6 is an enlarged longitudinalsection of the knotter and knot-drawing mechanism. Fig. 7 is a sectionalview of the same on the line y y of Fig. 6.

Fig. 12 is a section substantially on theline of Fig. 4 and illustrating the action of the knife. Fig. 13 is anenlarged bottom View of the knife and the knife-case as seen from theline 0cm of Fig. 12. Fig. 14 illustrates the cutting of the cord. Figs.15, 16, and 17 are sectional and perspective viewsillustratinga modifiedform of the knotter-hook. Fig. 18 illustrates a device illustrated inFigs. 15, 16, and 17 in position ready to tie the knot. Fig. 19 showsthe knot tied, but not tightened against the bundle. Fig. 20 is asectional view showing the hook drawn in, while the pressureplates holdthe untightened knot on the head and force the same against the bundle.Figs. 21, 22, 23, and 24 illustrate four successive positions of theparts from the beginning of the operation to the completion of thevsliding cam by which the knotter-hook is l IOO knot. Figs. 25, 26, 27,and 28illustrate four successive positions of the knotter and headduring the process of forming the knot with the mechanisms illustratedin Figs. 6 and 7.

Referring to the drawings and particularly to Figs. 6 to 11 and inconnection therewith Figs. 1 and 2,v the machine will be seen tocomprise three principal parts-the knotterhead mechanism, the knifemechanism, and the motive shaft, with its cams and gearwheel. The sleeve2 upon the base-plate 3 serves as a bearing for the hollow shaft 4,having a gear-pinion 5 upon its lower end and containing the slidablehead 6, which head in turn contains the slidable stem or rod 7, whichhas the hook 11 upon its upper end. The rod 7 is prevented from rotatingin the head 6 by the hook at its upper end, and the head 6 is preventedfrom rotating in the hollow shaft 4 by a key S. The head is providedwith a recess 9 to admit the heel lO of the hook 1l when it is drawninward. The head is turned, with the shaft 4, through the medium of thepinion 5 and the gear 12. The gear 12 is secured upon the motive shaft13, which has suitable bearings 14 and is driven through a gear 15 uponits opposite end. Both the pinion 5 and the gear 12 are mutilated gears,the gear l2 having the same number of .teeth as the pinion 5 and havinga liange 16 to engage a iiap or straight shoulder or face 17 upon thepinion and whereby the pinion is held against rotation during the timethe gear is completing its revolution. The shoulder 17 is releasedbefore the teeth of the two gears again engage. During the time thatlthe pinion, and hence the head and hook, is being rotated the stem orrod 7 is longitudinally stationary within the head. This is accomplishedby means of a sliding camplate 18, movable between suitable guides 19,extending from the base 3 and having upon its inner face an irregulargroove, (see Figs. 1 and 5,) a portion of which groove 20 issemicircular, and a portion 2l thereof is returned in a V form, thegroove having inclined sides. 22 is a pin on the face of the gear-wheel12 and entering the groove 20. While the gear-teeth are in mesh the pinwill move in the semicircular portion of the groove, so that thecam-plate, to which the lower end of the hook rod or stem 7 is attached,will not move; but as the gears pass out of the mesh the pin will moveinto the straight portions of the groove and pull the plate down duringone part of the revolution of the gear-wheel l2 and force it back intoposition during the remaining part of such movement. 23 is a bell-crankhaving a yoke 24, provided with lugs extending into the groove 25 in thehead G. The other arm of the bell-crank engages with the side cam 27upon the shaft 13, and before the hook is drawn down this cam acts tolift the head, this movement being to tilt the hook and make the cordsecure therein by closing the hook parts together before the hook isdrawn down into the head. The hook 11 is pivoted upon a pin 28 in theupper end of the rod 7, said upper end being bifurcated to receive thehook. The hook is provided with a heel 10, which is arranged beneath asmall crossbar section 29 of the head, there being sufiicient playbetween said heel and said crossbar section to permit the heel to swingout under said section when the hook is tilted on its pivot and drawndown into the head. Upon the upstroke of the hook after it has passedout of the head the heel engages the cross-bar 29 and tilts the hookdown to a horizontal position, as shown in Fig. 6. 30 is a tongue, alsopivoted on the pin 28 and adapted to close upon the hook 1l when it isdrawn into the head. A spring 3l holds the tongueor finger 30, butallows the same to yield at the time when the knot is drawn off inremoving the bundle from the machine. It will be noted that the rod 7 iseccentrically arranged in the head and the sleeve or shaft by which itis rotated. The rod, however, at its lower end is provided with anoffset portion 32, journaled in a block 33 on the camplate 18 andconcentric with the head. One side of the head is also out away, theobject being to form the knot in a position substantially in line withthe axis of the head, so that in turning the head, which is a part ofthe operation, the cord will simply be twisted and the knot will not beswung around or the string sawed on the bundle. This is a pai'- ticularfeature of our invention, as in the numerous experiments made withknottersnot so constructed much annoyance was experienced by thebreaking of the cords. One side or corner 34 of the head is beveled, sothat the string will slide up onto the top of the head easily and fromthence into the hook just as the revolution is completed. In the headare two transversely-slidable plates 35 and 36, onevbeing preferablywithin the other and adapted to close together on that side of theuntightened knot opposite the bundle when the hook is drawn down. Theirmovement is accomplished by means of the short levers 37 entering slots37' therein, as shown in Fig. 7, and pivoted in the head upon pins 33.The opposite or lower ends of the levers project into grooves 39 in thesides of the hook rod or stem 7. The bottoms of these grooves areparallel for a distance, so that the plates 35 and 36 are heldstationary until the hook passes beneath them. The bottoms of the upperparts of the grooves are inclined, so that the final movement of thestem causes the spreading of the lower ends of the levers and thepressing together of the plates 35 and 36 to retain the knot upon thetop of the head, instead of drawing it back into the head with the hook,and as the head moves up it rolls or forces the loose or unt-ightenedknot against the bundle to be tightened thereon by the hook drawing downthe ends of the cord.

A modied and, we think, a better form of knetter-hook is illustrated inFigs. 15 to 20,

IOO

inclusive. Th'e other parts of the device remain the same. This hookcomprises a fixed hook 40 upon the upper' end of the rod 7 and a tiltingpart comprising two fingers 41 and 42, provided, like the other device,with a heel 10, by which the fingers are swung from one position to theother. The finger 41 is provided with a slot 43 to admit the hook 40,and the finger 42 has an opening 44 to admit the point of the hook, asshown in Fig. 15. When the two strands of the cord have been drawn inbetween the two fingers, the fingers are tilted and said strands will bebound between the hook 40 and the finger 42, and obviously cannot escapetherefrom so long as the hook is drawn down into the shaft-hole in thehead.

The knife or cutting mechanism will be best understood by reference toFigs. 3, 4, and 12. The knife guide or case 45 is secured upon the frame46, which is pivoted upon a fixed shaft or rod 47, secured in the baseand parallel with the shaft 13. This frame is automatically swung towardthe hook of the knotter by a lever 48, engaged with a crank-pin 49 onthe disk 50. The pin is made adjustable by setting it upon anindependent adjustable plate 5l. The lever 48 is pivotedion the rod 47,and at its opposite end engages with a lug 52 on vthe knife-frame 46.The frame is held upon the lever byastrong tension-spring 53, which,however, permits the knife-frame to leave the lever in case it isnecessary to equalize the strain or tension upon the cord by allowingthe frame to yield and draw up toward'the head without being positivelymoved to such position by the lever. The movement to the positions shownin Fig. 3 by dotted lines is made to bring the knifeinto position tocatch the cord from the finger of the binder, and the cord is positivelymoved into line by means of a small finger 54, pivoted on the stud 55and connected by a link 56 to the knifeframe, (see Fig. 12,) whereby themovement of the finger is at all times commensurate with that oftheknifeframe to carry the cord into the notch 58 in the guard or case 45.The deeper portion 59 of this notch is intersected by the knife 60,which is a bar slidable in the case 45 and reciprocated therein by theside cam 61. The end of the knife is beveled or rounded, as shown at 62in Fig. 14, and the lower shoulder 63 of the notch 59 is also beveled toprevent the cutting of the cord between the bottom of the knife and thecase. The upper edge of the knife is sharp, and the cord is cutI betweenthe same and the shoulder 64 of the notch in the upper part of the caseor guide. At the moment the cord between the bundle and the binder-arm65 is moved into the notch 59 by the finger 54 the knife is drawn backby the action of the cam 6l, acting through the sliding frames 66 and67, which frames or arms are independent to permit the tilting orswinging of the knife-frame. At the next instant, just before the headof the knetter is lifted, the arm 66 in engagement with the cam 6l willdrop over the abrupt shoulder 68,

and the knife will be forcibly shot back to cut the string by the spring69, coiled on the rod 47, said arm 66 being held from turning on theshaft 47 by a pivoted link 66. The free end of the cord, with thatbefore liberated by drawing back the knife, may then be drawn throughthe loop, while the end of the cord in the binder-arm will be caught andheld in the knife-case, as shown in Fig. 14.

The complete operation of our machine will be Well understood byreference to Figs. 21 to 24. The base-plate 3 is secured to the frame 70of the bundling and binding machine. The machine partially illustratedin Fig. 21 is a lath-binder and is provided with compressorarms 71, (seedotted lin.es,) which compress and form the bundle preparatory to thewrapping of the cord aboutthe end thereof. 72 isa guard-plate and.cord-guide which overhangs the knetter-head, and the needle-arm 65 isprovided with a guard-plate 73, which as the arm is carried aroundbeneath the bundle will abut against the edge of the plate 72. The twoplates are provided with notches 74, which form a hole in which thevstring is guided and held opposite the knotter-hook and in line withthe axis ofthe head. The string or cord 75 is taken from a suitabletension roll or bobbin (not shown) and is threaded in the needle-arm 65and through the eye therein.

From thence it is carried downward and over the edge of the plate 72and4 thence past the hook and back to the knife-casing 45,in which it issecured. rlhe bundle or bunch of laths or other articles is then put inplace, whereupon the machine is ready to start and willthereafteroperateautomatically. Whenthe machine is started, theneedle-arm 65 will swing forward over the top of the bundle and thendownward and around beneath the same into the position shown in Figs.22, 23, and 24. The needle-arm remains in this position until the bundleis tied and removed. The downward movement of the needle-arm forms aloop around the bundle with both ends or strands of the loop caught uponthe forward side of the hook. At this time the head 6 receives onecomplete revolution fromthe gear 12 and in the direction shown by thearrows in Figs. 21 and 22. The ends 77 of the loop are carried up ontothe top of the head by the rounded corner thereof when the head isturned and are wrapped about the hook over the two loops which are onthe side thereof. The ends of the cord drop into the space between thetwo fingers of the hook, the knifeframe and the finger 54 havingmeantime been raised to the position shown in Fig. 23

to carry the strands of the cord into the knotter and prepare thecontinuous strand thereo f to be severedin the knife. Next follows theoperation of the knife, the same being drawn back by the cam 68,andafter the string is cut, with a new end left in the knife, the head 6 israised by the lever 23 to roll the loop or unfinished knot against thebundle,

IOO

thereby tilting the hook and closing the jaws thereof to confine theends of the cord therein. The ends of the cord are gripped so rmly thatthey will not slip in the hook, and with the head still raised to holdthe unfinished knot close to the bundle, as shown in Fig. 24, the rod 7and the hook are drawn down into the head to tighten the knot and thecord upon the bundle. The hookis then returned and the head dropped toopen the hook and free the ends of the cord therefrom. The bundle maythen be removed from the machine. After the return of the needle-arm,which follows, the machine is prepared to receive and bind the nextbundle.

It is obvious that various modiications of our invention will readilysuggest themselves to one skilled in the art, and we therefore do notconfine the same to the specific construction herein shown anddescribed.
